From first- to third-generation biofuels: Challenges
First-generation biofuels include ethanol and biodiesel and are directly related to a biomass that is more than often edible. Ethanol is generally produced from the fermentation of C6 sugars (mostly glucose) using classical or GMO yeast strains such as Saccharomyces cerevisiae. Only a few different feedstocks, mostly sugarcane or corn, are actually...MDPI
Biofueling Our Future with Agriculture : USDA ARS
RS: First-generation biofuels refer to liquid transportation fuels produced from sugar or starch crops such as sugarcane or corn, respectively, or edible oils such as soybean oil. In the United States, most of the ethanol generated would be considered a first-generation biofuel as it is produced from corn grain.

Generation Biofuels an overview ScienceDirect Topics
Generation Biofuels. First generation biofuels (ethanol in particular) face three major criticisms: (1) intensification of their use leads to competition with food resources (the
Recent Developments in Lignocellulosic Biofuels, a Renewable
First-generation biofuel is primarily derived from parts of edible plants (i.e., grains and oilseeds). These types of fuel have derived from sugar, starch, vegetable oil, and fats. Examples of most popular first-generation biofuels are biodiesel, ethanol, biofuel gasoline, biogas, etc. [7,13,24,26].
Biofuels and their sources of production: A review on
The first-generation biofuels have several advantages but suffer from significant limitations such as; a. involvement in the food chain and direct competition
Promising evolution of biofuel generations. Subject review
First-generation biofuels produced from edible biomass such as starch (from potato, wheat, barley, and corn) or sugars (from sugarcane and sugar beet), initially showed a promising capability in minimizing the fossil fuels combustion and lowering atmospheric levels of CO2 which is consumed by crops as they grow [13].
Recent advances and viability in biofuel production
As the demand for fuels extracted from a feedstock of edible oil increases, non-edible oils such as neem oil, castor, and jatropha oils are taken up for the
The potential of biofuels from first to fourth generation
In contrast to second-generation biofuels, the third-generation processes completely decouple biofuel production from the need for agricultural land. Additionally, algal-based oil production is likely greater than that in higher plants, as lipids mainly accumulate in specific parts of the plant (e.g., in rape seeds), while in algae, each cell
